To all whom t may ooacem.'

' Bje it known that l, JACK H. BEvEL, citizenof the United States,residing at Dallas, in the County of Dallas and State of Texas, haveinvented certain new and useful llmprovements in Measuring Devices, ofwhich the following is a specification.

v'llhis invention relates to new and useful improvements in measuringdevices.

The invention has particularly to do with measuring devices for use inascertaining the depth of a' well and involves revolving measurin-gelements co-acting with the cable which is lowered into the well andoperating a register whereby each foot of travel of the f cable downwardis indicated;

In carrying out'the invention l provide a jointed framevcarrying a pairof measuring wheels having grooved faces and pro? vided with tensionmeans whereby the cable is gripped between the wheels. One of the wheelsoperates a register once during each revolution thus registering thetravel of the cable between the wheels. A particular feature is thearrangementv of the frame-which is provided with a hinged joint on oneside opposite the'point where the cable passes between the wheels and acoupling joint on the other side having a removable fastening; wherebythe frame may be broken open by removing the fastening, so that one' ofthe wheels will be swung away from the other, the cable released and anopening` provided -in the side of the frame whereby .the cable may beswung out of the frame,

or the frame removed from the cable. This arrangement affords a solidand substantial frame whereby the wheels are held in alinement when theframe is coupled together and also whereby the spring tension wheel doesnot lose its adjustment when the frame is broken. Supports are providedfor the frame whereby it may be positioned on the top of a well casingand suitably held. The supportsmay be so constructed as to permit ofadjustment for casings of various diameters.

The invention will be more readily understood from a reading of theJfollowing' speelfication and by reference to the accompanying drawings,in which an example of the invention is shown, and wherein: n Fig. 1 isa side elevation of a device constructed vin accordance with myinvention,

and

Fig. 2 is` a plan view of the same.-

In the drawings the numeral 10 designates an elongated supportingl framewhich comprisesra stationary section or yoke 11 and a swinging sectionor yoke 12. The yokes are joined together .at their ends which are atthe center of the frame by a hinged joint 13. At the opposite side ofthe frame the ends of the yoke` are provided with intermeshing ears 14perforated to receive a locking pin l5 whereby a coupling joint is had.When the pin l5 is in place the yokes` are connected and form va'rigidframe. When the pin is removed the yoke 12 may be freely swung on thehinged joint 13 away from the yoke 1l1 ets 22 on the sides of the yoke.rllhe springs are placed under tension by the screws 21 and thus exertpressure upon the airle through means of the stirrups whereby'the wheel1 8 is placed under tension. A wheel 23 having a grooved face is mounted-on an axle 24: fixed inthe yoke 11. `'.llhe wheel 23 has a width lessthan that of the wheel 18 so as to be received relatively within thegroove of the wheel 18. By this arrangement the cable A ismoreeiiciently gripped between the grooved faces of the wheels as willbe evident from Fig. 2. The spring tension devices exert suilicientpressure on the wheel 18 as .to cause the same togrip the cableincooperation with the wheel 23.

The yoke l1 has its outer end fastened on provided with an ofset steppedbracket 27. A similar upright 251 is providedl for the yoke at theopposite end of the frame. The upright 251 has a shoulder 261 at itslower end and a stepped bracket 271. `Keeper plates 28 are secured tothe outer sides .of the shoulders 26 and 261 and each platev car.- riesa setscrew 29. The shoulders 26 and 261 may rest on the upper edge of awell casing B so that the keeper plates will overhand the outside ofsaid casing and may be fastened thereto by the set screws 29. Forcasings of smaller diameters angular brackets 30 are fastened to thestepped yportions of the brackets 27 and 271 by bolts 31 .the uppershouldered end of an upright'25 having a shoulder 26 at its lower endand and may be adjusted to form a jaw for eachv upright to fit over theupper edge of the casing, each bracket 30 being provided with a setscrew '32 as will be obvious.

5 The upright 251 has at its upper end an outwardly directed support orbracket 33. An angular support or hanger 34 is fastened to the outer endof the yoke 12. A bolt 35 is passedthrough these partsfand receives awing nut 36 whereby the yoke 12 is suitably fastened on the upright 251.It will be seen that through the agency of the couplingl joint involvingthe fastening pin 15 and the support at the end of the 15 yoke 12employing the fastening bolt 35, the frame 10 will be rigidly sustainedand the wheels 18 'and 23 properly held in alinement and caused toproperly operate. It will be appreciated that if the parts of the 2 0frame are not substantially fastened that there is a change for lostmotion and a variation in the mechanism; also uneven wear would be had.0n one side of the yoke 11 a suitable register 37 is mounted andprovided with an operating finger 38 which projects into the path of alateral pin 39 carried by the wheel 23.- Thus once during eachrevolution of the wheel 23 the pin 39 rides over the finger 38 andoperates the register so as to record the revolutions of said wheel. Thewheel may have such a diameter as to traverse a certain standard ofmeasurement along the cable at each revolution, and thus a certainnumber of revolutions ofthe wheel 23 will total a measurement in feetAand inches. It is obvious that various kinds of recording devices couldbe used and they form no part of the invention. When it 4.0 is desiredto remove the cable it is merely necessary to withdraw the pin 15 andremove the bolt 35. After this has been done the yoke 12'may be swungbackward and away from the yoke 11 whereby the ears 14 are separated andthe frame broken, an opening thus being provided in the side of theframe through which the cable may be displaced. Thejroke may. berestored to position or it may be opened as described to receive thecable when it is desired to measure the depthof the well. yoke has beenremoved from the cable the measuring device may be removed from the wellcasing and likewise replaced when desired.

What I claim, is: 1. In a measuring device of the character described, apair of substantially horizontal U-shaped frame sections having theiropen ends arranged innermost, a hinge joint connecting the inner ends ofcorresponding sides After the of th frame sections whereby one framesection may be swung horizontally with ielation to the other framesection and the frame section securely held against percepti blevertical movement with relation to ,each other', a plurality of aertured ears formed upon the inner end of the opposite side of one framesection, a plurality of apertured ears formed upon the inner end of theopposite side of the other frame section and adapted to interfit withthe first named apertured ears, a pin adapted for insertion through theapertured ears so that they are securely locked together and one framesection held against vertical movement with relation to the other framesection, a friction wheel arranged within and supported by one framesection, a co-acting friction wheel arranged within and supported by theother frame section and adapted to move bodily toward and away from thefirst named friction wheel, yielding means to urge the second namedfriction wheel toward the first named friction wheel, a registersupported upon one frame section near one friction wheel and actuatedthereby, and supports attached to the outer ends of the U-shaped framesections and depending therefrom.

2. In a measuring device of the character described, a substantiallyhorizontal frame, a friction wheel mounted within the frame, a co-actingfriction wheel ymounted within the frame, yielding means to move onefriction wheel toward the other friction wheel, a register carried bythe frame and operated by one friction wheel, uprights secured to theends of the frame and provided at their lower ends with step edbrackets, and clamps adapted to be a justably secured to thesteppedbrackets.

3. In a measuring device, a frame, fric-- tion wheels mounted within theframe, a register supported by the frame and operated by one frictionwheel, an upright rigidly secured to one end of the frame and providedat its lower end with a stepped bracket, a clamp adapted to beadjustably secured to the stepped bracket, an extension secured to theopposite end of the frame and projecting longitudinally and outwardlyfrom the frame, an upright provided at its upper end with a horizontalange adapted to contact with said extension, a bolt adjustablyconnecting the flange and extension, a stepped bracket formed upon thelower end of the last named upright, and a clamp adapted to beadjustably secured to the last named stepped bracket.

In testimony whereof I aiiix my signature.

JACK H. BEvEL.
